rx4 0.3.2

//! rx4 — the agent harness engine with full pi protocol compatibility.
//!
//! Models write. rx4 gives them tools, memory, loops, permissions, sessions,
//! and control planes. Hosts (CLIs, TUIs, IDEs) embed rx4.
//!
//! # Safety
//!
//! This crate is `#![forbid(unsafe_code)]` — no unsafe code is allowed anywhere.

#![forbid(unsafe_code)]
//!
//! Pi-compatible: JSONL v3 sessions, RPC over stdin/stdout, pi tool names,
//! extension protocol with capability policy, SDK surface.
//!
//! ```no_run
//! use rx4::Agent;
//!
//! # #[tokio::main]
//! # async fn main() -> Result<(), Box<dyn std::error::Error>> {
//! let mut agent = Agent::new();
//! agent.set_scope(rx4::Scope::Coding);
//! agent.prompt("fix the failing test").await?;
//! # Ok(())
//! # }
//! ```
